A Great Lake Watch column. After the warmest winter on record, state water managers say the lake has hit its annual ceiling — and we're only at the start of May.

Smaller than your fingernail. Older than Lake Bonneville. Worth $40 to $60 million a year to Utah, and the difference between life and death for millions of migrating birds. The Great Salt Lake's brine shrimp are the lake's quietest — and most telling — story.

Big names showed up for the Great Salt Lake this week. The Miller, Maggelet, and Marriott families pledged $30 million to Great Salt Lake Rising — the coalition working to restore the lake before the 2034 Olympics. But the director of the organization said it plainly: "What can I do to save the lake? If everybody asked that, we'd be a lot further along." Here's where the money goes, who's behind the effort, and how you can help — at any level.

Scientists have a number: 4,198 feet. That is the minimum elevation at which the Great Salt Lake functions as a healthy ecosystem. As of this spring, the lake sits at 4,192 feet — nearly six feet below that threshold. Getting back there will require more water, delivered consistently, over many years. Here is where that water comes from — and where it has been going instead.

The Great Salt Lake is shrinking. That's no longer a distant worry — it's a measurable reality with consequences that reach directly into the lungs of every family living along the Wasatch Front. This is what the science says, and what it means for you.
